/* /the-lab/oxidative-load/ OLI methodology page: section styles from the batch-2 master
   saniservice-science-oxidative-load.html. Global chrome (nav/footer/buttons .cta|.btn-*),
   reset, body, .wrap, h1-h3, .serif, .eyebrow + responsive hero type come from style.css +
   responsive.css; only this page's section vocabulary lives here. NO stat band: this is an
   100svh full-viewport content hero, NOT the .hero-unit system. The master's
   min-height:90vh and the .ac-hero h1 clamp(2.6rem,6vw,5rem) are dropped; responsive
   header.ac-hero h1{var(--hero-h1)} owns heading size. responsive.css relaxes header.ac-hero
   to min-height:auto at <=860 (homepage hero-unit); this sheet loads after, so the refills
   below keep the no-stat hero at 100svh (and fill on phone). :target + reduced-motion guard
   added (absent in the master). */
